Background: Long non-coding RNAs (lncRNAs) have been reported to participate in various diseases. Hirschsprung disease (HSCR) is a common digestive disease in the new born. However, the relationship between lncRNAs and HSCR remains unclarified.
Methods: We used qRT-PCR to detect the relative expression of LOC101926975 in 80 pairs of HSCR bowel tissues and matched normal bowel tissues. CCK-8 assay, transwell assay and flow cytometry were then used to evaluate the function in vitro by knocking down the LOC101926975 in SK-N-BE(2) cells. Receiver operating characteristic (ROC) curve was used to evaluate the potential diagnostic value of LOC101926975.
Results: LOC101926975 was significantly downregulated in HSCR tissues with excellent correlation with FGF1. Dysregulation of LOC101926975 suppressed cell proliferation and induced G0/G1 arrest without impact on cell apoptosis or migration. Meanwhile, the AUC of LOC101926975 was 0.900 which presented great diagnostic value.
Conclusions: Our study firstly investigates the potential function of LOC101926975 in HSCR and infers that LOC101926975 can distinguish HSCR from the normal ones.
